Efficacy and Safety of Dupilumab in Adolescents With Uncontrolled Moderate to Severe Atopic Dermatitis: A Phase 3 Randomized Clinical Trial

Importance

Adolescents with atopic dermatitis (AD) have high disease burden negatively affecting quality of life, with limited treatment options. The efficacy and safety of dupilumab, a monoclonal antibody, approved for treatment in adolescent patients with inadequately controlled AD, remain unknown in this patient population.

Objective

To assess the efficacy and safety of dupilumab monotherapy in adolescents with moderate to severe inadequately controlled AD.

Design, Setting, and Participants

A randomized, double-blind, parallel-group, phase 3 clinical trial was conducted at 45 US and Canadian centers between March 21, 2017, and June 5, 2018. A total of 251 adolescents with moderate to severe AD inadequately controlled by topical medications or for whom topical therapy was inadvisable were included.

Interventions

Patients were randomized (1:1:1; interactive-response system; stratified by severity and body weight) to 16-week treatment with dupilumab, 200 mg (n = 43; baseline weight <60 kg), or dupilumab, 300 mg (n = 39; baseline weight ≥60 kg), every 2 weeks; dupilumab, 300 mg, every 4 weeks (n = 84); or placebo (n = 85).

Main Outcomes and Measures

Proportion of patients with 75% or more improvement from baseline in Eczema Area and Severity Index (EASI-75) (scores range from 0 to 72, with higher scores indicating greater severity) and Investigator's Global Assessment (IGA) 0 or 1 on a 5-point scale (scores range from 0 to 4, with higher scores indicating greater severity) at week 16.

Results

A total of 251 patients were randomized (mean [SD] age, 14.5 [1.7] years; 148 [59.0%] male). Of 250 patients with data available on concurrent allergic conditions, most had comorbid type 2 diseases (asthma, 134 [53.6%]; food allergies, 60.8%; allergic rhinitis, 65.6%). A total of 240 patients (95.6%) completed the study. Dupilumab achieved both coprimary end points at week 16. The proportion of patients with EASI-75 improvement from baseline increased (every 2 weeks, 41.5%; every 4 weeks, 38.1%; placebo, 8.2%) with differences vs placebo of 33.2% (95% CI, 21.1%-45.4%) for every 2 weeks and 29.9% (95% CI, 17.9%-41.8%) for every 4 weeks (P < .001). Efficacy of the every-2-week regimen was generally superior to the every-4-week regimen. Patients in the dupilumab arms had higher percentage values of conjunctivitis (every 2 weeks, 9.8%; every 4 weeks, 10.8%; placebo, 4.7%) and injection-site reactions (every 2 weeks, 8.5%; every 4 weeks, 6.0%; placebo, 3.5%), and lower nonherpetic skin infections (every 2 weeks, 9.8%; every 4 weeks, 9.6%; placebo, 18.8%).

Conclusions and Relevance

In this study, dupilumab significantly improved AD signs, symptoms, and quality of life in adolescents with moderate to severe AD, with an acceptable safety profile. Placebo-corrected efficacy and safety of dupilumab were similar in adolescents and adults.

Dupilumab Provides Favorable Safety and Sustained Efficacy for up to 3 Years in an Open-Label Study of Adults with Moderate-to-Severe Atopic Dermatitis

BACKGROUND

Management of moderate-to-severe atopic dermatitis (AD) commonly requires long-term treatment.

OBJECTIVE

The aim of this study was to report the safety and efficacy of dupilumab treatment for up to 3 years in adults with moderate-to-severe AD.

METHODS

This ongoing, multicenter, open-label extension study (LIBERTY AD OLE; NCT01949311) assessed dupilumab treatment in adults previously enrolled in dupilumab trials. Patients received dupilumab 300 mg weekly up to 148 weeks. The primary outcome was safety.

RESULTS

Of 2677 patients enrolled and treated, 347 reached week 148. Mean self-reported drug compliance was 98.2%. Safety data were consistent with previously reported trials (270.1 adverse events [AEs]/100 patient-years; 6.9 serious AEs/100 patient-years) and the known dupilumab safety profile. Common AEs (≥ 5% of patients) included nasopharyngitis, AD, upper respiratory tract infection, conjunctivitis, headache, oral herpes, and injection-site reactions. AD signs and symptoms showed sustained improvements during treatment with mean (standard deviation, mean percentage change from parent study baseline) Eczema Area and Severity Index 1.4 (3.2, - 95.4%) and weekly Pruritus Numerical Rating Scale 2.2 (1.8, - 65.4%) at week 148.

LIMITATIONS

No control arm; fewer patients at later time points; regimen different from the approved 300 mg every 2 weeks dose.

CONCLUSION

These safety and efficacy results support dupilumab as a continuous long-term treatment for adults with moderate-to-severe AD.

Association of Rituximab Use With Adverse Events in Children, Adolescents, and Young Adults

IMPORTANCE

Rituximab is among the most frequently used immunotherapies in pediatrics. Few studies have reported long-term adverse events associated with its use for children.

OBJECTIVE

To describe the use of rituximab and to assess whether its use is associated with short- or long-term adverse events, infections, or time to immune reconstitution in a diverse group of young people.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study included 468 patients aged younger than 21 years who received rituximab for diverse indications between October 1, 2010, and December 31, 2017, at Texas Children's Hospital, a large pediatric referral hospital. Patterns of adverse events, infections, and immune recovery are described. Data analyses were conducted from December 2019 to June 2020.

EXPOSURE

One or more doses of rituximab.

MAIN OUTCOMES AND MEASURES

Adverse drug events (eg, anaphylaxis), incidence of mild and severe infections, and time to recovery of B lymphocyte subset counts and immunoglobulin levels. Survival models and logistic regression analyses and were used to identify associated risk factors of infectious and noninfectious adverse drug events.

RESULTS

We identified 468 patients receiving at least 1 dose of rituximab. The total follow-up time was 11 713 person-months. Of the 468 patients, 293 (62.6%) were female, the median (interquartile range) age at receipt of dose was 14.3 (9.9-16.8) years, and 209 (44.7%) were self-reported White Hispanic. Adverse events associated with rituximab infusion occurred in 72 patients (15.4%), and anaphylaxis occurred in 17 patients (3.6%). Long-term adverse events, such as prolonged neutropenia and leukoencephalopathy, were absent. Infections occurred in 224 patients (47.9%); 84 patients (17.9%) had severe infections, and 3 patients (0.6%) had lethal infections. Concurrent use of intravenous chemotherapy, treatment of systemic lupus erythematosus, neutropenia, and use of intravenous immunoglobulin were associated with increased risk of infection. Among 135 patients (28.8%) followed up to B cell count recovery, CD19+ or CD20+ cell numbers normalized in a median of 9.0 months (interquartile range, 5.9-14.4 months) following rituximab use; 48 of 95 patients (51%) evaluated beyond a year had low-for-age B cell counts. Recovery of CD27+ memory B cell number occurred in a median of 15.7 months (interquartile range, 6.0-22.7 months). Among patients with normal baseline values, low immunoglobulin G (IgG) levels developed in 67 of 289 patients (23.2%) and low IgM levels in 118 of 255 patients (40.8%); of these patients evaluated beyond 12 months from rituximab, 16 of 117 (13.7%) had persistently low IgG and 37 (33.9%) of 109 had persistently low IgM.

CONCLUSIONS AND RELEVANCE

Rituximab is well tolerated among young people and is associated with few serious adverse events, but infections are common, corresponding to a prolonged period of B cell count recovery often lasting for longer than a year. Further examination of strategies to prevent infections following rituximab should be pursued.

Immunogenicity and Safety of Reduced-Dose Intradermal vs Intramuscular Influenza Vaccines: A Systematic Review and Meta-analysis

IMPORTANCE

Low-dose intradermal influenza vaccines could be a suitable alternative to full intramuscular dose during vaccine shortages.

OBJECTIVE

To compare the immunogenicity and safety of the influenza vaccine at reduced or full intradermal doses with full intramuscular doses to inform policy design in the event of vaccine shortages.

DATA SOURCES

MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched for studies published from 2010 until June 5, 2020.

STUDY SELECTION

All comparative studies across all ages assessing the immunogenicity or safety of intradermal and intramuscular influenza vaccinations were included.

DATA EXTRACTION AND SYNTHESIS

Data were extracted by a single reviewer and verified by a second reviewer. Discrepancies between reviewers were resolved through consensus. Random-effects meta-analysis was conducted.

MAIN OUTCOMES AND MEASURES

Primary outcomes included geometric mean titer, seroconversion, seroprotection, and adverse events.

RESULTS

A total of 30 relevant studies were included; 29 studies were randomized clinical trials with 13 759 total participants, and 1 study was a cohort study of 164 021 participants. There was no statistically significant difference in seroconversion rates between the 3-µg, 6-µg, 7.5-µg, and 9-µg intradermal vaccine doses and the 15-µg intramuscular vaccine dose for each of the H1N1, H3N2, and B strains, but rates were significantly higher with the 15-µg intradermal dose compared with the 15-µg intramuscular dose for the H1N1 strain (rate ratio [RR], 1.10; 95% CI, 1.01-1.20) and B strain (RR, 1.40; 95% CI, 1.13-1.73). Seroprotection rates for the 9-µg and 15-µg intradermal doses did not vary significantly compared with the 15-µg intramuscular dose for all the 3 strains, except for the 15-µg intradermal dose for the H1N1 strain, for which rates were significantly higher (RR, 1.05; 95% CI, 1.01-1.09). Local adverse events were significantly higher with intradermal doses than with the 15-µg intramuscular dose, particularly erythema (3-µg dose: RR, 9.62; 95% CI, 1.07-86.56; 6-µg dose: RR, 23.79; 95% CI, 14.42-39.23; 9-µg dose: RR, 4.56; 95% CI, 3.05-6.82; 15-µg dose: RR, 3.68; 95% CI, 3.19-4.25) and swelling (3-µg dose: RR, 20.16; 95% CI, 4.68-86.82; 9-µg dose: RR, 5.23; 95% CI, 3.58-7.62; 15-µg dose: RR, 3.47 ; 95% CI, 2.21-5.45). Fever and chills were significantly more common with the 9-µg intradermal dose than the 15-µg intramuscular dose (fever: RR, 1.36; 95% CI, 1.03-1.80; chills: RR, 1.24; 95% CI, 1.03-1.50) while all other systemic adverse events were not statistically significant for all other doses.

CONCLUSIONS AND RELEVANCE

These findings suggest that reduced-dose intradermal influenza vaccination could be a reasonable alternative to standard dose intramuscular vaccination.

Prevalence of COVID-19 vaccines (Sputnik V, AZD-1222, and Covaxin) side effects among healthcare workers in Birjand city, Iran

Background

The prevalence of vaccine side effects plays an important role in public perception about vaccination programs. This study was designed to investigate the side effects of the first dose of COVID-19 vaccine; Sputnik-V, AZD-1222, and Covaxin.

Methods

A study was performed to evaluate the side effects of these vaccine among 503 health care workers in Birjand (Iran). Our study used the questionnaire consisted of 4 main categories including demographic data, previous COVID-19 infection, vaccine information, and local and systemic side effects of vaccines.

Results

81.9%, 88.8%, and 92.9% of people who have been vaccinated with Sputnik-V, AZD1222, and Covaxin vaccines, respectively, have reported at least one side effect. The prevalence of systemic side effects in AZD-1222 vaccine was higher than Sputnik V and Covaxin vaccines. Injection site pain (62.1%), fatigue (43.9%), muscle pain (42.5%), and fever (40.6%) were the most common side effects in all three vaccines. Side effect frequency was higher in the female group (90.6%) than the male group (79.5%). The prevalence of side effects with Sputnik V and Covaxin vaccines was reduced in the elderly. Moreover, the prevalence of side effects was higher in the case of convalescent patients (92.4 %) than in the group with no history of infection. The prevalence of side effects was higher in person with a BMI above 25 in the AZD-1222 and Covaxin vaccines.

Conclusions

The most common side effects of the Sputnik-V, AZD-1222, and Covaxin vaccine among Birjand (Iran) healthcare workers were injection site pain, muscle pain, fatigue, fever, and headache. Age and gender were the most important variables in the prevalence of vaccine side effects.

Harm reduction for the treatment of patients with severe injection-related infections: description of the Jackson SIRI Team

INTRODUCTION

Hospitalizations for severe injection-related infections (SIRI), such as endocarditis, osteomyelitis, and skin and soft tissue infections (SSTI) are increasingly common. People who inject drugs (PWID) experiencing SIRIs often receive inadequate substance use disorder (SUD) treatment and lack of access to harm reduction services. This translates into lengthy hospitalizations with high rates of patient-directed discharge, readmissions, and post-hospitalization mortality. The purpose of this study was to describe the development of an integrated "SIRI Team" and its initial barriers and facilitators to success.

MATERIALS AND METHODS

The Jackson SIRI Team was developed to improve both hospital and patient-level outcomes for individuals hospitalized with SIRIs at Jackson Memorial Hospital, a 1550-bed public hospital in Miami, Florida, United States. The SIRI Team provides integrated infectious disease and SUD treatment across the healthcare system starting from the inpatient setting and continuing for 90-days post-hospital discharge. The team uses a harm reduction approach, provides care coordination, focuses on access to medications for opioid use disorder (MOUD), and utilizes a variety of infection and addiction treatment modalities to suit each individual patient.

RESULTS

Over the initial 8-months of the SIRI Team, 21 patients were treated with 20 surviving until discharge. Infections included osteomyelitis, endocarditis, bacteraemia/fungemia, SSTIs, and septic arthritis. All patients had OUD and 95% used stimulants. All patients were discharged on MOUD and 95% completed their prescribed antibiotic course. At 90-days post-discharge, 25% had been readmitted and 70% reported taking MOUD.

CONCLUSIONS

A model of integrated infectious disease and SUD care for the treatment of SIRIs has the potential to improve infection and addiction outcomes. Providing attentive, patient-centered care, using a harm reduction approach can facilitate engagement of this marginalized population with the healthcare system.KEY MESSAGESIntegrated infectious disease and addiction treatment is a novel approach to treating severe injection-related infections.Harm reduction should be applied to treating patients with severe injection-related infections with a goal of facilitating antibiotic completion, remission from substance use disorder, and reducing hospital readmissions.

Twice-Yearly Lenacapavir for HIV Prevention in Men and Gender-Diverse Persons

BACKGROUND

Twice-yearly subcutaneous lenacapavir has been shown to be efficacious for prevention of human immunodeficiency virus (HIV) infection in cisgender women. The efficacy of lenacapavir for preexposure prophylaxis (PrEP) in cisgender men, transgender women, transgender men, and gender-nonbinary persons is unclear.

METHODS

In this phase 3, double-blind, randomized, active-controlled trial, we randomly assigned participants in a 2:1 ratio to receive subcutaneous lenacapavir every 26 weeks or daily oral emtricitabine-tenofovir disoproxil fumarate (F/TDF). The primary efficacy analysis compared the incidence of HIV infection in the lenacapavir group with the background HIV incidence in the screened population. The secondary efficacy analysis compared the incidence of HIV infection in the lenacapavir group with that in the F/TDF group.

RESULTS

Among 3265 participants who were included in the modified intention-to-treat analysis, HIV infections occurred in 2 participants in the lenacapavir group (0.10 per 100 person-years; 95% confidence interval [CI], 0.01 to 0.37) and in 9 participants in the F/TDF group (0.93 per 100 person-years; 95% CI, 0.43 to 1.77). The background HIV incidence in the screened population (4634 participants) was 2.37 per 100 person-years (95% CI, 1.65 to 3.42). The incidence of HIV infection in the lenacapavir group was significantly lower than both the background incidence (incidence rate ratio, 0.04; 95% CI, 0.01 to 0.18; P<0.001) and the incidence in the F/TDF group (incidence rate ratio, 0.11; 95% CI, 0.02 to 0.51; P = 0.002). No safety concerns were identified. A total of 26 of 2183 participants (1.2%) in the lenacapavir group and 3 of 1088 (0.3%) in the F/TDF group discontinued the trial regimen because of injection-site reactions.

CONCLUSIONS

The HIV incidence with twice-yearly lenacapavir was significantly lower than the background incidence and the incidence with F/TDF. (Funded by Gilead Sciences; PURPOSE 2 ClinicalTrials.gov number, NCT04925752.).

Why are so huge differences reported in the occurrence rate of skin lipohypertrophy? Does it depend on method defects or on lack of interest?

Lipohypertophy (LH) is the most common skin complication of incorrect injection technique which does not only represent an aesthetic defect but also severely disrupts insulin pharmacokinetics/pharmacodynamics. As a consequence of that, hormone release is delayed and unexplained/unpredictable hypoglycemia occurs, both deteriorating metabolic control while negatively affecting adherence to treatment and quality of life. The economic burden due to unwanted intra-LH injections is accounted for by inappropriately high insulin requirements, increased emergency-related hospitalizations, and loss of work days. Greater attention has to be paid by diabetes care teams to education programs with periodic refreshers to achieve better metabolic control and reduce the economic burden of diabetes.

Tissue Response to Subcutaneous Infusion Catheter

Insulin infusion pump, continuous glucose monitoring (CGM), and insulin infusion set (IIS) have been developed to be increasingly feasible for people with type 1 diabetes (T1D). Several recently approved CGMs are transitioning from 7-day to 10-day wear time without the need for fingerprick recalibration. Nevertheless, studies and improvements on IIS, a critical part of insulin pump therapy, have been limited. In particular, the recommended wear time of IIS is still 2-3 days, which can hardly match the current duration of CGM for potential closed-loop system development. It is generally believed that both the inserted catheter and the subsequent infused insulin drug could induce particular subcutaneous tissue response and skin-related complications at the infusion site. In certain cases, poor glycaemic control, increased risk of hypoglycemia, and serious cosmetic impact on people with diabetes were observed. Skin complication has also been attributed as an important factor resulting users to discontinue insulin pump therapy. This article provides the rare systematic review of IIS induced subcutaneous tissue responses and skin complications, including the impacts from the inserted catheters, the subcutaneous infused insulin, and the adhesive or tape used to immobilize the catheter. The FDA's recommendation for the frequency of IIS change was further discussed. Future studies on this topic are required to further understand the IIS-related problems, and future strategies could be developed accordingly to significantly reduce the incidence of these problems, extend the wear time, and increase the acceptance of insulin pump based therapy.

Efficacy and safety of live varicella zoster vaccine in diabetes: a randomized, double-blind, placebo-controlled trial

AIMS

To elucidate varicella zoster virus (VZV)-specific cell-mediated immunity and humoral immunogenicity against live attenuated Oka varicella zoster vaccine concurrently vaccinated with 23-valent pneumococcal polysaccharide vaccine (PPSV23) in elderly people with diabetes mellitus.

METHODS

This double-blind randomized controlled single-centre study of 60-70-year-old people with diabetes compared immunity and safety profiles 3 months after one dose of varicella zoster vaccine or placebo. PPSV23 was immunized simultaneously. Primary analysis evaluated cell-mediated immunity using the VZV skin test. Secondary analyses were a VZV interferon-γ enzyme-linked immunospot (ELISPOT) assay and immunoadherence haemagglutination test. Adverse experiences were recorded using diary questionnaires.

RESULTS

By intent-to-treat analysis, 27 participants with diabetes who had been administered the vaccine were compared with 27 participants who were given a placebo. Changes in skin test scores were 0.41 ± 0.80 and 0.11 ± 0.93 (P = 0.2155), and geometric mean fold rises of the ELISPOT counts were 1.2 [95% confidence interval (CI) 0.2, 7.9] and 1.2 (95% CI 0.2, 7.3) (P = 0.989) in the vaccine and placebo groups, respectively. The geometric mean titre did not increase 3 months after vaccination in either group. No vaccination-related severe adverse experience was reported and no participant developed herpes zoster.

DISCUSSION

Our previous results demonstrated that varicella zoster vaccine safely enhanced VZV-specific immunity in elderly people with or without diabetes. The results of this study showed that varicella zoster vaccine can be used safely, but it cannot boost virus-specific immunity in elderly people with diabetes when administered with concurrent PPSV23. Alternative strategies are needed to prevent VZV-associated diseases in this population.

Ganetespib in Combination with Pemetrexed-Platinum Chemotherapy in Patients with Pleural Mesothelioma (MESO-02): A Phase Ib Trial

PURPOSE

Ganetespib, a highly potent, small-molecule Heatshock protein 90 inhibitor, has potential efficacy in malignant pleural mesothelioma (MPM) via activity on critical survival pathways and known synergies with antifolates and platinum chemotherapy. We conducted a dose-escalation study to identify the maximum tolerated dose (MTD) of ganetespib in patients with chemotherapy-naïve MPM.

PATIENTS AND METHODS

MESO-02 (ClinicalTrials.gov: NCT01590160) was a nonrandomized, multicenter, phase Ib trial of 3-weekly ganetespib (100 mg/m2, 150 mg/m2, 200 mg/m2; days 1 and 15) with pemetrexed (500 mg/m2; day 1) and cisplatin (75 mg/m2; day 1) or carboplatin (area under concentration-time curve 5; day 1) in patients with MPM. Dose escalation was performed using the 3 + 3 design (cisplatin) and accelerated titration design (carboplatin). Secondary endpoints included best response, progression-free survival (PFS), and pharmacogenomic analyses.

RESULTS

Of 27 patients enrolled (cisplatin, n = 16; carboplatin, n = 11), 3 experienced dose-limiting toxicities: grade 3 nausea (cisplatin, n = 1; carboplatin, n = 1) and grade 2 infusion-related reaction (carboplatin, n = 1). Ganetespib's MTD was 200 mg/m2. Partial response was observed in 14 of 27 patients (52%; 61% in 23 response-evaluable patients) and 13 of 21 (62%) with epithelioid histology. At the MTD, 10 of 18 patients (56%) had partial response, 15 of 18 (83%) had disease control, and median PFS was 6.3 months (95% CI, 5.0-10.0). One responder exhibited disease control beyond 50 months. Global loss of heterozygosity was associated with shorter time to progression (HR 1.12; 95% CI, 1.02-1.24; P = 0.018).

CONCLUSIONS

Ganetespib can be combined safely with pemetrexed and platinum chemotherapy to treat patients with MPM. This class of agent should be investigated in larger randomized studies.

Botulinum toxin type A versus 5-Fluorouracil in treatment of keloid

Most therapeutic approaches for keloids remain clinically unsatisfactory. In the last years, intralesional botulinum toxin-A (IL BTX-A) was proposed for treatment of keloids. Our aim of the study was to compare the clinical efficacy of IL BTX-A and IL 5-Fluorouracil (IL 5-FU) in treatment of keloids. A total of 50 patients with keloids were included in the study, 22 patients (with 26 keloids) were treated with IL BTX-A monthly for up to 6 months and other 22 patients (with 27 keloids) were treated with IL 5-FU weekly for up to 6 weeks, while the remaining 6 patients, each having multiple keloids, were treated with both IL BTX-A for some lesions (8 keloids) and IL 5-FU for their remaining lesions (8 keloids). The clinical improvement was assessed according to flattening of the lesions. Side effects were recorded. A significantly better therapeutic response of keloids was detected after IL BTX-A than IL 5-FU (P = 0.041). IL BTX-A achieved excellent and good flattening of the lesions (58.8% and 20.6%) compared to (31.4% and 17.1%) after IL 5-FU, respectively. In BTX-A treated group, there was no statistically significant difference between the clinical response in small lesions compared to medium and large ones (P = 0.476). While in 5-FU treated group, small and medium lesions showed significantly better response than larger ones (P = 0.009). IL BTX-A caused fewer side effects than IL 5-FU, less pain, itching, no hyperpigmentation and less recurrence. Both IL BTX-A and IL 5-FU showed positive results in treatment of keloids. However, IL BTX-A showed higher clinical efficacy even in large size keloids with less side effects.

Impact of Medicare Continuous Subcutaneous Insulin Infusion Policies in Patients With Type 1 Diabetes

BACKGROUND

The Centers for Medicare and Medicaid Services (CMS) has numerous requirements for coverage of continuous subcutaneous insulin infusion (CSII; insulin pump). Due to recent improvements in diabetes treatment, people with type 1 diabetes are living longer, resulting in an increase in the number of individuals who are eligible for Medicare and are impacted by CMS policies regarding CSII.

METHODS

Two hundred forty-one adults with type 1 diabetes who had been on CSII with CMS coverage for at least 6 months were surveyed. Median age was 67 years, mean A1c was 7.0%, 64% were women, 93% were white, and the median type 1 diabetes duration was 42 years. Participants reported median CSII use of 15 years and 82% were on CSII before starting CMS.

RESULTS

Of those starting CSII while on CMS, challenges included cost of supplies (29%) or the insulin pump (24%). The majority (57.5%) reported issues with obtaining supplies, the most common problems being delays in release of supplies (29%), difficulty getting paperwork completed (23.5%), and seeing a health care provider every 90 days (18%). Participants reported changing their CSII behaviors because of supply delays (39%) including leaving site in place >3 days (64%), and reusing pump supplies (34%). Consequently, participants reported adverse outcomes including more erratic (48%) or higher (42%) blood glucose and pain or irritation at sites (34%).

CONCLUSION

This study concluded that current CMS CSII policies promote adverse CSII behaviors and outcomes in type 1 diabetes and thus call for changes in the CMS CSII policies.

Safety of BCG vaccination and revaccination in healthcare workers

BCG vaccination and revaccination are increasingly being considered for the protection of adolescents and adults against tuberculosis and, more broadly, for the off-target protective immunological effects against other infectious and noninfectious diseases. Within an international randomized controlled trial of BCG vaccination in healthcare workers (the BRACE trial), we evaluated the incidence of local and serious adverse events, as well as the impact of previous BCG vaccination on local injection site reactions (BCG revaccination). Prospectively collected data from 99% (5351/5393) of participants in Australia, Brazil, Spain, The Netherlands and the UK was available for analysis. Most BCG recipients experienced the expected self-limiting local injection site reactions (pain, tenderness, erythema, swelling). BCG injection site itch was an additional common initial local symptom reported in 49% of BCG recipients. Compared to BCG vaccination in BCG-naïve individuals, BCG revaccination was associated with increased frequency of mild injection site reactions, as well as earlier onset and shorter duration of erythema and swelling, which were generally self-limiting. Injection site abscess and regional lymphadenopathy were the most common adverse events and had a benign course. Self-resolution occurred within a month in 80% of abscess cases and 100% of lymphadenopathy cases. At a time when BCG is being increasingly considered for its off-target effects, our findings indicate that BCG vaccination and revaccination have an acceptable safety profile in adults.

Safety and efficacy of trastuzumab administered as a 30-min infusion in patients with HER2-positive advanced gastric cancer

PURPOSE

To investigate the safety and efficacy of 30-min maintenance infusions of trastuzumab in advanced gastric cancer positive for human epidermal growth factor receptor 2 (HER2).

METHODS

This was a retrospective study conducted across five Korean hospitals in patients with HER2-positive gastric or gastroesophageal junction adenocarcinoma treated with first-line, 3-weekly trastuzumab plus chemotherapy. The first dose of trastuzumab (8 mg/kg) was administered as a 90-min infusion, with all subsequent maintenance infusions (6 mg/kg) given over 30 min. The primary aim was to investigate infusion-related reactions and cardiac events with 30-min infusions of trastuzumab. Objective response rate, progression-free survival, and overall survival were secondary endpoints.

RESULTS

The study included 128 patients (efficacy population), of whom 123 received both induction and maintenance infusions and formed the safety population. The median age was 63 years; 80% were presenting for the first time with metastatic disease, and 94% were treated with trastuzumab plus capecitabine/cisplatin. Infusion-related reactions were observed in 32 of 123 patients (26%). There were no cardiac events. The most frequent adverse events were anorexia and nausea, followed by vomiting, fatigue, mucositis, sensory neuropathy, and hand-foot syndrome. Most events were grade 1-2 and were manageable. No patient discontinued study treatment due to adverse events. The objective response rate was 63%, and included 6 complete responses.

CONCLUSIONS

Trastuzumab 30-min maintenance infusions were well tolerated with a good safety profile, and resulted in sustained efficacy in patients with HER2-positive advanced gastric cancer.

A Systematic Review and Meta-Analysis of Injection Site Reactions in Randomized-Controlled Trials of Biologic Injections

BACKGROUND

Biologic agents are emerging as an important treatment option for immune-mediated diseases. Injection site reactions following subcutaneous injection of biologic agents is not well described in the literature.

OBJECTIVE

To summarize injection site reaction data in phase 3 trials of all biologic agents.

METHODS

MEDLINE, Embase, and CENTRAL databases were systematically searched on February 8, 2022. Proportional meta-analysis was conducted to summarize injection site reaction prevalence for each biologic.

RESULTS

There were 158 articles included in the review. The most common types of injection site reactions were erythema (42.8%), unspecified reaction (23.3%), pain (12.4%), and pruritus (5.7%). No patients discontinued their treatment due to injection site reactions in 39 of the 48 studies that reported on discontinuation data. There were 16 biologics included in meta-analysis across 80 eligible studies. The biologics with the highest point prevalence of patients reporting injection site reactions were Canakinumab (15.5%; 294 patients), Dupilumab (11.4%; 1888 patients), Etanercept (11.4%; 4363 patients), and Ixekizumab (11.2%; 2205 patients). The biologics with the lowest point prevalence of injection site reactions were Risankizumab (0.8%; 707 patients), Brodalumab (1.3%; 1365 patients), Guselkumab (1.3%; 1852 patients), Secukinumab (1.9%; 1277 patients).

CONCLUSIONS

The prevalence of injection site reaction in response to biologics ranges from 0.08 to 15.5%. Canakinumab, Dupilumab, Etanercept, and Ixekizumab had the highest prevalence of injection site reactions. Risankizumab, Brodalumab, Guselkumab, and Secukinumab had the lowest prevalence of injection site reactions. Recommendations are made regarding the improvement of adverse event reporting to better understand the epidemiology of injection site reactions.

Immunogenicity and safety of a second dose of a measles-mumps-rubella vaccine administered to healthy participants 7 years of age or older: A phase III, randomized study

The introduction of vaccination programs against measles, mumps, and rubella (MMR) led to significant global reduction in morbidity and mortality from these diseases. The currently recommended MMR vaccination schedule in the United States of America comprises 2 vaccine doses typically administered at 12-15 months and 4-6 years, respectively. Considering recent outbreaks in the USA, catch-up vaccination with an additional dose of MMR vaccine could contribute to outbreak control and community protection. This phase III, observer-blind, randomized controlled trial (NCT02058563) assessed the immunogenicity and safety of a dose of the MMR-RIT vaccine (Priorix, GSK) compared to MMR II vaccine (control; M-M-R II, Merck&Co Inc.) in ≥7-year-olds who had received ≥1 previous dose of MMR vaccine. We assessed anti-measles, anti-mumps, and anti-rubella antibody geometric mean concentrations (GMCs; primary endpoint) and seroresponse rates (SRRs) at day 42 post-vaccination. Solicited, unsolicited, and serious adverse events (AEs) were recorded. The according-to-protocol cohort for immunogenicity included 869 participants (MMR-RIT: N = 433; MMR II: N = 436). We observed anti-measles, anti-mumps, and anti-rubella antibody GMCs of 1790.2 mIU/mL, 113.5 EU/mL, and 76.1 IU/mL, respectively, and SRRs of 98.8%, 98.4%, and 99.5%, respectively, after a dose of MMR-RIT; non-inferiority compared to MMR II was demonstrated. Both vaccines showed comparable reactogenicity profiles; the most common solicited AEs were injection site redness and pain, and fever (MMR-RIT: 12.2%, 11.8%, and 3.0%; MMR II: 11.7%, 11.5%, and 5.2%, respectively). The dose of MMR-RIT induced robust immune responses that were not inferior to those of MMR II, and was well tolerated.

Infections associated with diabetic-care devices

BACKGROUND AND AIMS

There are more than 463 million people living with diabetes with this number expected to increase to 700 million people by 2045. Diabetes is a risk factor for patients developing various comorbidities including, but not limited to, diabetic neuropathy, retinopathy, chronic kidney disease, vascular impediments, and infections. Due to the continuous invasiveness of monitoring and/or treatment of this disease, site for infections are elevated.

METHODS

Information was primarily gathered by employing various PubMed scholarly articles for real-world examples in addition to data extraction from supplementary manuscripts. Key search words employed were: diabetes, insulin site infection, lancing infections, insulin pump associated infections, and continuous glucose monitoring infections.

RESULTS

Diabetic care devices used for blood glucose monitoring and insulin administration are an integral part of the disease management and/or treatment in various settings including patient homes, assisted living facilities, community centers, and hospitals. These invasive devices leave a diabetic patient with a small open wound which may get infected or aid in blood borne pathogen transmission. Since diabetes itself has a morbidity and mortality burden, it is important to also study complications arising from the management of diabetes.

CONCLUSION

Although cases exist of infections, either by pathogen transmission or direct inoculation of the prick site, these are a very small percentage and thus should not undermine the confidence in diabetes management. This review highlights the instances of these infections and where they most often occur.

BCG Revaccination for the Prevention of Mycobacterium tuberculosis Infection

BACKGROUND

In a previous phase 2 trial, bacille Calmette-Guérin (BCG) revaccination was not shown to provide protection from primary Mycobacterium tuberculosis infection but prevented sustained M. tuberculosis infection, defined by an initial conversion on a QuantiFERON-TB (QFT) test (an interferon-γ release assay) from negative to positive, followed by two additional positive QFT tests at 3 and 6 months after the initial conversion (a secondary end point). A vaccine efficacy of 45% (95% confidence interval [CI], 6 to 68) was observed.

METHODS

We performed a phase 2b, double-blind, randomized, placebo-controlled trial to evaluate the efficacy of BCG revaccination, as compared with placebo, for the prevention of sustained QFT test conversion (primary end point) in QFT test-negative, human immunodeficiency virus (HIV)-negative adolescents. Adverse events were assessed in a secondary analysis, and immunogenicity was assessed in an exploratory analysis. Vaccine efficacy was evaluated in the modified intention-to-treat population, which included all the participants who had undergone randomization, received the BCG vaccine or placebo, and had a negative QFT test 10 weeks after receipt of BCG vaccine or placebo; the last criterion was added to exclude participants with M. tuberculosis infection around the time that the vaccine or placebo was administered. Hazard ratios and 95% confidence intervals were estimated from a stratified Cox proportional-hazards model.

RESULTS

A total of 1836 participants underwent randomization; 918 received the BCG vaccine, and 917 received placebo. After a median 30 months of follow-up, a sustained QFT test conversion was observed in 62 of 871 participants in the BCG-vaccine group and 59 of 849 participants in the placebo group. The hazard ratio for a sustained QFT test conversion (BCG vaccine vs. placebo) was 1.04 (95% CI, 0.73 to 1.48), for a vaccine efficacy point estimate of -3.8% (95% CI, -48.3 to 27.4). Adverse events occurred more frequently in the BCG-vaccine group than in the placebo group, and most were due to injection-site reactions (pain, redness, swelling, and ulceration). BCG revaccination induced cytokine-positive type 1 helper CD4 T cells.

CONCLUSIONS

BCG revaccination in QFT-test negative, HIV-negative adolescents did not provide protection from sustained M. tuberculosis infection. (Funded by the Gates Foundation; ClinicalTrials.gov number NCT04152161.).

RTS,S/AS01E malaria vaccine (MoSQUIRIX*) Children living in malaria-endemic regions: little efficacy, poorly documented harms

Malaria remains a major public health problem in most tropical coun- tries. Plasmodium falciparum infection can be life-threatening, especially in children. Insecticide-treated bed nets have been shown to reduce deaths due to malaria among young children. A malaria vaccine (RTS,S/AS01E) containing two adjuvants has been assessed for its ability to prevent P. falciparum malaria among young children living in endemic areas. The clinical data have been analysed by the European Medicines Agency (EMA) in conjunction with the World Health Organization (WHO). Efficacy has been evaluated in sub-Saharan African countries. Two trials including a total of more than 16 000 children aged 6 weeks to 17 months compared the malaria vac- cine with a rabies vaccine or a menin- gococcal vaccine. Most of the children were healthy, had ready access to healthcare, and were protected with bed nets. In these trials, three injections of the malaria vaccine one month apart did not reduce overall mortality or malaria mortality in low-mortality settings. In the year following vaccina- tion, the risk of malaria episodes was reduced by about 30% among children aged 6 to 12 weeks and by about 50% among those aged 5 to 17 months.The incidence of severe malaria was only reduced in the older age group. Vac- cine efficacy waned rapidly over time, even with a booster dose at 18 months. During clinical trials, reactions at the injection site and systemic reac- tions were more frequent with the malaria vaccine than with the compara- tor vaccines. Febrile seizures during the days following vaccination were 2 to 5 times more frequent with the malaria vaccine among children aged 5 to 17 months. The malaria vaccine may also carry a risk of meningitis, as well as a risk of pneumonia among HIV-infected children and premature infants.

Injection site reactions after dupilumab or tralokinumab for atopic dermatitis

Background: Injection site reaction (ISR) is a local phenomenon defined as a constellation of symptoms, including swelling, erythema, pruritus, and pain around the site of injection.Objective: ISR is reported as a frequent adverse event after subcutaneous injection (SCI) of several biologics.Methods: We performed an observational real-life study to compare dupilumab and tralokinumab as regards ISR, analysing frequency, duration and intensity of symptoms related to SCI. From January 2023 to June 2023, we enrolled adult patients affected by moderate to severe AD and being on dupilumab or tralokinumab treatment. A 12 items questionnaire was administered to all enrolled patients.Results and conclusions: Three hundred and ninety-two patients were included. ISR was a frequent occurrence in both the treatment groups, with tralokinumab causing ISR more frequently than dupilumab. However, the reactions were generally mild and no patient stopped therapy.

An Evaluation of VYC-17.5L for Forehead Contouring: A Prospective, Open-Label, Post-Marketing Study

BACKGROUND

Forehead contouring can be achieved using injectable fillers. VYC-17.5L is a filler containing 17.5 mg/mL of hyaluronic acid (HA) with lidocaine (3 mg/mL) for the treatment of skin depressions due to premature aging. Prior studies have demonstrated the safety and efficacy of VYC-17.5L in nasolabial folds, lips, and radial cheek lines, but little has been published on the effectiveness of VYC17.5L for forehead contouring.

AIMS

This prospective, open-label, post-marketing study conducted in France evaluated the effectiveness and safety of the HA injectable filler VYC-17.5L for use in forehead contouring.

METHODS

Adults (≥ 18 years) with irregularities of forehead contouring received VYC-17.5L in the forehead on Day 1 with an optional touch-up on Day 14. Effectiveness was assessed via investigator-rated Global Aesthetic Improvement Scale (GAIS) of "improved" or "much improved" from baseline at month 1 (M1). Secondary endpoints included participant-rated GAIS and FACE-Q Satisfaction with Facial Appearance. Injection site reactions (ISRs) and adverse device effects (ADEs) were assessed throughout the study.

RESULTS

Eighty subjects completed the study. The primary endpoint was met: 97.5% of participants showed improvement on the investigator GAIS. Participant GAIS scores were also improved. FACE-Q scores significantly improved from baseline (p < 0.0001) and were sustained through month 12. Most ISRs were mild or moderate and resolved in ~1 week. Nine subjects (11%) reported ADEs, with the majority being mild or moderate; the most common ADE was pain, which resolved in < 15 days.

CONCLUSION

VYC-17.5L was well tolerated and effective for improving forehead contouring, as demonstrated by improvements in investigator- and participant-rated measures.

Safety and Tolerability of Ixekizumab: Integrated Analysis of Injection-Site Reactions from 11 Clinical Trials

<p>BACKGROUND: Injection-site reactions (ISRs) are reported with biologic therapies. The objective of this study was to comprehensively characterize ISRs among moderate-to-severe psoriasis patients treated with ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin (IL)-17A.</p> <p>METHODS: ISRs are presented from UNCOVER-1, UNCOVER-2, and UNCOVER-3 (12 weeks) and all ixekizumab-exposed patients in 11 controlled and uncontrolled trials (156 weeks).</p> <p>RESULTS: At week 12, reported ISR frequency with 80 mg ixekizumab every 2 weeks (IXE Q2W, 16.8%) was comparable with etanercept twice weekly (16.4%); both were significantly higher than placebo (3.3%). With IXE Q2W, ISRs were mild (12.3%), moderate (3.9%), or severe (0.7%), typically reported in the first 2 weeks (median onset, 6.6 days), and most commonly characterized as nonspecified, erythema, and pain. Generally, erythema onset was delayed, whereas pain occurred around drug administration. Discontinuation from ixekizumab due to ISRs (0.4%) occurred in the first 12 weeks. After 2 weeks, ISR frequency decreased and remained stable (≤4.2%) through week 156. No ISR-related serious adverse events were reported in ixekizumab-treated patients. ISR data were solicited if patients reported injection-associated events. Since nonspecified ISR was the most commonly reported term, specific types might be underreported.</p> <p>CONCLUSIONS: ISRs have been reported with ixekizumab during clinical trials. These reactions are typically tolerable, manageable, and decrease over time.</p> <p>Clinicaltrials.gov: NCT01474512 (UNCOVER-1); NCT01597245 (UNCOVER-2); NCT01646177 (UNCOVER-3); NCT01777191 (UNCOVER-A); NCT01624233 (UNCOVER-J); NCT01107457 (I1F-MC-RHAJ); NCT02561806 (I1F-MC-RHBS); NCT02387801 (I1F-US-RHBO);NCT02513550 (I1F-MC-RHBP); NCT02634801 (I1F-EW-RHBZ)</p> <p>J Drugs Dermatol. 2018;17(2):200-206.</p> <p>THIS ARTICLE HAD BEEN MADE AVAILABLE FREE OF CHARGE.</p> <p>PLEASE SCROLL DOWN TO ACCESS THE FULL TEXT OF THIS ARTICLE WITHOUT LOGGING IN.</p> <p>NO PURCHASE NECESSARY.</p> <p>PLEASE CONTACT THE PUBLISHER WITH ANY QUESTIONS.</p>.

Surveillance of adverse events following immunisation in Australia, 2015

This report summarises Australian passive surveillance data for adverse events following immunisation (AEFI) for 2015 reported to the Therapeutic Goods Administration and compares them to long-term trends. There were 2,924 AEFI records for vaccines administered in 2015; an annual AEFI reporting rate of 12.3 per 100,000 population. There was a decline of 7% in the overall AEFI reporting rate in 2015 compared with 2014. This decline in reported adverse events in 2015 compared to the previous year was mainly attributable to fewer reports following the HPV vaccine and replacement of monovalent vaccines (Hib, MenCCV and varicella) with combination vaccines such as Hib-MenC, and MMRV. AEFI reporting rates for most individual vaccines were lower in 2015 compared with 2014. The most commonly reported reactions were injection site reaction (26%), pyrexia (17%), rash (16%), vomiting (8%) and headache (7%). The majority of AEFI reports (85%) were described as non-serious events. There were two deaths reported, but no clear causal relationship with vaccination was found.

The Use of Facial Fillers in Clinical Practice: The Level of Patient Satisfaction and an Overview of Common Clinical Complications

BACKGROUND

Patient esthetic satisfaction following facial fillers is an essential topic that should be studied as the number of individuals seeking treatment increases. The face is an essential component of the human body that is frequently associated with beauty, youthfulness, and health. Individuals may seek facial augmentation with fillers for a variety of reasons, such as congenital, acquired by means of aging or disease, or current aesthetic trends.

OBJECTIVE

The aim is to assess patient's aesthetic satisfaction and description of common clinical complications in relation to the facial filler injections.

METHOD

A cross sectional survey using a questionnaire derived from the global aesthetic improvement scale and WHO quality of life scale, convenience sampling was used to recruit patients attending cosmetic clinics, descriptive analysis and Chi-square methods were used to analyze the data.

RESULTS

In the study, 500 female participants, with an average age of 28.48 years, were included. Over 90% reported improvement after filler treatment, ranging from improved to very much improved. A statistically significant correlation was observed between patient satisfaction and the number of filler treatments and the anatomical injection site. However, no statistically significant correlation was found when considering age groups. Local side effects, such as swelling and redness at the injection site, were common but generally mild and of short duration.

CONCLUSION

Although the satisfaction level is currently high, practitioners in the field need to pay more attention to this important outcome, since understanding the patient's motivation and expectation before proceeding with the procedure is very important and can contribute significantly in determining patient satisfaction with the result.
